The German under-19 international is said to have a big future with Forest, and has been moved across the Trent in order to gain further first team experience.
McParland knows him well, having worked closely with him during his time as a coach and then temporary manager at the City Ground.
Bastians usually oparates wide left, but can also play on the right or through the middle if required and has been brought in with Myles Weston again struggling with his long-term hamstring problem.
The 19-year-old broke into the Reds first team in the 2005/06 season - Forest's first at League One level - making two starts and a further nine substitute appearances in the league, and one substitute showing in the FA Cup.
The following season proved to be a hectic one for the attack-minded player, despite only making two substitute appearances under new boss Colin Calderwood at Forest.
Instead he spent time out on loan. First he went to Conference outfirt Northwich Victoria, appearing five times and scoring once, before a further spell in the Conference with Halifax Town where he made ten appearances and found the net four times.
That brought him to the attention of Forest's League One rivals Gillingham, who didn't hesitate to give him a chance to prove he could cut it at that level, as he spent a month there, making five appearances and hitting his first ever Football League goal.
Bastians will be no stranger to Meadow Lane having figured in Forest's 2-1 win here in the controversial pre-season friendly in July.
He played 90 minutes in that one, and looked a talented player as he switched from right to left wing and added a touch of class to the Forest side.
His duel with Gary Silk that day was one of the bright spots of the game, and he later switched to the right wing to held combat the Notts threat of Weston who first suffered his hamstring trouble later in that game.
Despite a promising and commited display, Bastians had only a bit part role at the start of this season on the red side of the Trent, playing 70 minutes of Forest's penalty shoot out win over Chester in the Carling Cup, 12 of their 2-1 home league defeat to Leeds, and the full match as Peterborough dumped them from the Johnstone's Paint Trophy 3-2.
He has however only just returned to the City Ground from a successful stint with Chesterfield.
Bastians joined the Spireites shortly after Notts' 1-0 win over them, and went on to make five starts in his first month there, before his loan was extended right up to Christmas.
In total he started 13 games for them, and scored their crucial equaliser as
His most recent appearance came against rivals Mansfield Town, as he helped Chesterfield record a comfortable 2-0 derby day win with a fine showing.
At Saltergate Bastians has just been replaced by Manchester United winger Michael Barnes who has joined on a month's loan - allowing McParland to make his move.
The winger is also a more than adept set-piece taker, and is likely to be handed the responsibility of Notts' corners, given that the role has been shared out between several players so far this campaign.
Reports of his matches at Chesterfield consistently describe him as the Spireites' chief threat, and a pacey player who likes to whip early balls into the box.
Following his debut match against Wrexham, Chesterfield boss Lee Richardson said this of Bastians' immediate impact: "He showed a good early touch and demonstrated his capability. He gave us width on the left and showed us he is capable of using the width to his advantage."
One thing is certain, if Bastians is as successful with Notts as he was at Chesterfield, the Magpies will surge up the table.
